The flashing 11 may be a single or multireaches the proper height, spreads the usual ply flashing to suit the requirements of any layer of mortar and then, instead of bricks,

have shown a two-ply flashing including top roof joining structure in the wall substanand bottom plies 12 and 13 respectively. As tially in the same manner in which bricks are clearly shown in Figs. 1 and 2, the top'ply 12 incorporated. The wall is built over the roof extends beyond the bottom ply, this being for oining element ust as though bricks had the purpose of forming a so-called feather been placed in the wall. Thus, it appears that there is no material departure in the manner of constructing the wall when incorporating my improved roof joining element. If desired to more securely anchor the wall member, suitable ties may be extended from the wall member to adjacent parts of the wall in a manner quite similar to the manner in which stone facing or the like is often tied to a wall structure. H

To facilitate handling of the roof joining unit, I prefer to roll, fold orotherwise bundle the free or exposed portion of the flashing strips adjacent the outside surface of the wall block. This may be done by rolling the free part of the flashing strip as indicated in Fig. .4, and the rolled or otherwise bundled strip may be temporarily maintained in such condition'by suitable means such as one or more clips 21. The clips 21 may be in the form of staples to embrace the rolled part'of the flashing, the legsof the staples being driven in the top and bottom sections of the body member. As shown in Fig. 4, the clip 21 is in the form of a hook member having its long leg driven in the lower section 16 of the wall block, and its upper .leg terminating short'of the top member 15. In this instance, the hook member is of bendablemetal which permits the hook to' be opened up merely by bending the same outwardly and downward- 1y whereby the bundled flashing strip is released. Obviously, the holding means may be either merely bent downwardly and left substantially flat against the wall, or it may be completely removed from the block memher if desire In the present instance, I have shown the body member 10 as being divided in a plane extending at an angle to the top and bottom faces of the wall block. By so disposing the line of separation, I avoid to some extent a sharp bend in the flashing strip at the point where it enters the wall block. This arrange.- ment also is desirable in that the embedded portionl'l' of the flashing strips are held at a water shedding angle so that water which might accidently find its way-between the upper and lower sections is not apt to work its 'way across the entire width of the embedded portion to the interior ofthe wall.

1 For facilitating the formation of lapped joints between the ends of adjacent roof joining units, 1 provide an offset end arrangement as shown inFigs. 1 and 3. An end portion of the top section 15 of the wall member and a similar end portion of the bottom section,16 at the oppositeend of the wall mem her is cut away as indicated at 22 and 23 re spectively. The flashing strip, however, and its embedded marginal portion extends lon gitudinally of the wall member the full length of the combined top and bottom sections 15 and16 as clearly shown. By reference to Fig.3,"it will be seen that-the top section 15 of the wall block at one end overlaps the projecting end of the bottom section 16 of the adjacent end of an adjacent roof joining unit. Also, that the adjacent portions of the flashing 1111 overlap in a sim As clearly shown in Fig. 2, the flashing 11 overlaps roofing material layers 25 and 26, the latter having marginal portions turned upwardly against the face of the wall as indicated at 27, while the flashing 11 is dis posed over the upturned marginal portions 27 and over the adjacent portions of the roofing plies so that the roofing material, in the corners around the roof where the latter oins the wall, is materially reinforced. The various overlapped elements and joints will, of course, be cemented together with roofing material in accordance with well-known practice to prevent leakage between the joints and a protective covering may be applied in the customary manner.

The flashing strips 12 and 13 may be made of any, suitable impervious sheet material; for instance, tar paper or the like, but I prefer to make the flashings of suitable fabric such as canvas, which is impregnated with waterprooflng material. Such canvas flashings are not apt to break or crack when the of which should be determined by reference to the following claims, the same being construed as broadly as possible consistent with the state of the art.

I claim as my invention:

1. A 'unitary'roof joining structure comprising a wall member and a flashing having a marginal portion embedded in said wall member, the free or exposed portion of said flashing being bundled adjacent one side of said wall member, and means for temporarily maintaining said flashing in bundled condition to facilitate handling of said unit.

2. A roof oining structure fabricated into a unit before installation thereof in a building structure, comprising a wall block and a flashing having a marginal port-ion secured to said block, said flashing extending longitudinally of the block and having one end substantially coincident with one end of the block and the other end extending beyond the other end of the block for facilitating the formation of a lapped joint with the flashing of another, similar roof joining unit.

3. A unitary roof joining structure comprising a wall member and a flashing having a marginal portion embedded in said wall member intermediate its thickness, a portion of said wall member above said embedded marginal flashing portion at one end, and a similar end portion of the wall member below said embedded marginal flashing portion at the other end of the structure, being cut away to facilitate the formation of lapped joints between the structure and similar juxtaposed structures.

4. In a roof joining, the combination of a wall block including top and bottom members, and a flashing strip having a marginal portion disposed between said top and bottom members, the latter being united so as to form, with said flashing, a unitary structure, the block part of which is adapted to be incorporated in a building wall structure when the latter is being built, a portion of the top member of said wall block at one end thereof and a similar portion of the bottom member at the other end of-the wall block being cut away to facilitate the format-ion of lapped joints between the flashing strip of the structure and the flashing strips of similar juxtaposed structures.

5. A roof joining structure adapted to be fabricated into a unitary structure in a factory and subsequently incorporated in a building structure, comprising a wall member and a flashing having a portion secured to said member, the free or exposed portion of said flashing being bundled adjacent one side of said wall member to facilitate handling and installation of the wall member in a building wall when the latter is being built, said bundled flashing being adapted to be subsequently spread out to operative position.

6. A roof joining structure adapted to be fabricated into a unitary structure in a factory and subsequently incorporated in a building structure, comprising a wall member and a flashing having a marginal portion embedded in said member so as to provide a substantially impervious joint between said flashing and wall member, the free or exposed portion of said flashing being bundled adjacent one side of said wall member to facilitate handling and installation of the Wall member in a building wall when the latter is being built, said bundled flashing being adapted to be subsequently spread out to operative position.

7. As an article of manufacture, a preformed roof joining device including a wall member and a flashing having a marginal edge attached to said wall member, the free portion of said flashing being bundled adjacent said wall member, and means to retain said flashing in a bundled condition.

8. As an article of manufacture, a preformed roof joining device including a wall member and a flashing attached to said wall member, said flashing being bundled adjacent said wall member.
